我在其中一个用户的Silverlight中收到以下错误。目标运行时是4.1.10329.0，应用程序是使用Silverlight 4构建的。我不会理解可能存在的问题。看起来它正试图在LoadComponent上加载一些东西并失败：
Message: Unhandled Error in Silverlight Application
Parser_CreateFromValue_CannotConvertInitializationText]
Arguments: PropertyChanged,System.Windows.Data.UpdateSourceTrigger

关于可能出现什么问题的任何想法？
